What is the max number of channels generally needed for giant scale?

I use the 14SG.

Was there one servo per Rx channel? What radio were you using?

I originally set it up as one servo per channel on my 28X but I also switched it over to Xbus as an experiment.

I run my 35% on a dx 9. Only problem is if I want to put smoke on it I'll have to run match boxes to free up a channel or two instead of using the 4 separate aileron inputs. Considering I prefer the simplicity of less things to go wrong and smoke really just adds weight for a small cool factor I doubt I will add smoke unless one day I decide to upgrade to an 18.

So let's say I am doing a gasser and have 4 aileron servos, 2 elevator servos, rudder throttle, kill, and smoke. (Am I missing anything?)
If I run servo per Rx channel, that is 10 channels, so one short on a 9 ch Tx.
But if I run one of the bus systems, how many Rc channels would I need?

 

[jamesrxx951]

you could use a XG6 using nothing but Xbus. 1 channel for 4 ailerons with a 4 port converter. 1 channel for both elevators, 2 port converter or use a 4 port and program rudder to run on rudder channel. Throttle, ignition kill, and smoke will also be on 1 converter that is 4 port. Not sure what programming options are on the XG6 though but I suspect minimal mixing, programming etc. My suggestion would be get the 14. it is a radio that can grow with you for the price.

If you use matchboxes on the ailerons you'll free up 2 channels on the 9. And have one to spar. If my understanding of how they works is correct any way. 1 matchbox for each wing

Yep. @IMAC FANATIC ran his 40center with a DX-7.

 

[IMAC FANATIC]

Yup, but a DX8. Fantastic radio, never let me down.
Upgraded to a qq18 lately, couldn't run a full house glider with all the mixes on the 8 .

 

[TazmanianDevil]

7 channels.
Ele 2
Ail 2
Throt 1
Rudd 1
Engine cut off 1

I tried to look up some info on Matchbox, but I didn't find a whole lot. How is using a JR matchbox different than using something like one of the bus protocols? Does the Matchbox let you mix different servo brands in the same system (maybe one brand for the throttle and another brand for ailerons)?

Do I understand it correctly that, using the 7 Channel example above, if I used 2 Matchboxes (one fore aileron and one for elevator) that I would only use 5 channels on the transmitter?
